David I was plagued by the same problem yesterday until I shut off forkMode in maven-surefire-plugin e.g. <build><plugins> <plugin> <artifactId>maven-surefire-plugin</artifactId> <configuration> <forkMode>never</forkMode></configuration> I also upped the MaxHeap and PermGen params in _JAVA_OPTIONS environment variable e.g. _JAVA_OPTIONS: -Xmx3192m -XX:MaxPermSize=3192m Viel Gluck, Martin ______________________________________________ Verzicht und Vertraulichkeitanmerkung
